Abstract
Embodiments of the present disclosure provide medium or high voltage fuses that employ spiral wound elements supported by rods, which may replace the usages of a ceramic core. In particular, the use of rods to wind and fix spiral fuse elements provides increased reliability by minimizing the fuse elements from drifting within the fuse assembly.
Claims18
A fuse assembly comprising:
- two end plates;
- a plurality of rods coupled to the end plates, wherein, for each of the plurality of rods, a first end of the rod is coupled to a first end plate of the two end plates and a second end of the rod is coupled to a second end plate of the two end plates, and wherein each of the plurality of rods is detached and radially spaced from each of the other rods;
- and
- a spherical fuse element that is conductively coupled to the two end plates, wherein the spherical fuse element is wound around the plurality of rods in a helical fashion.
1 more element
A method of manufacturing a fuse assembly, the method comprising:
- configuring each of two end plates with a plurality anchor points;
- positioning a plurality of rods between the two end plates, wherein, for each of the plurality of rods, a first end of the rod is coupled to one of the anchor points of a first end plate of the two end plates and a second end of the rod is coupled to another of the anchor points of a second end plate of the two end plates, and wherein each of the plurality of rods is detached and radially spaced from each of the other rods;
- winding a spherical fuse element around the set of the plurality of rods in a helical fashion, wherein the spherical fuse element is conductively coupled to the two end plates.
